A Camp Pendleton Marine was detained for questioning after military police found a 14-year-old girl at a barracks on the base on June 28. (Gregory Bull/Associated Press)More than 80 days after a missing 14-year-old girl was found in a Camp Pendleton barracks, her family says they've received few details about the investigation or those who brought the girl onto the military base. An online petition created by Perez is demanding that the name of the Marine be released to the family, that an impartial investigation be completed and that Camp Pendleton adopt measures to prevent similar incidents. Perez said the family has received calls from detectives who said the investigation is moving along but provided few specific details. The MPO, relatives said, would have also revealed the Marine's name to the girl and her family.
